Answer:

13

Step-by-step explanation:

$f(x) = \dfrac{x}{2} + 8$

$f(10) = \dfrac{10}{2} + 8$

$f(10) = 5 + 8$

$f(10) = 13$

To find the height of the peak, list the corresponding sides and angles of the two triangles you and Tyler have created. (6 poin

sukhopar [10]

We know that

Right triangles PBM and MTF are similar
because
angle PMB=angle TMF
and
angle BPM=angle FTM
and
angle B =angle F=90 degrees
so
corresponding sides are
BM and MF
PB and TF
PM and MT
(PB/TF)=BM/MF
solve for PB
PB=(TF*BM)/MF
where
TF=6ft
BM=20 ft
MF=3 ft
so
PB=(6*20)/3------> 40 ft

the answer is
<span>the height of the peak is 40 ft</span>

Answer:

C: (1,3)

Step-by-step explanation:

If we count 1 to the right on the x-axis and count 3 up on the y-axis, we will end up at the point of intersection which is (1,3).

MN is a diameter of a circle with centre ' O ' . If BD = CD , prove that ∠OAD = ∠OCD

Varvara68 [4.7K]

Answer:

$\sf \: Proved \: \angle \: OAD \: = \angle \: OCD$

Step-by-step explanation:

<em>Given:</em>

Mn is diameter of circle having centre O

and BD = OD,

<em><u>To prove that:</u></em>

<u> $\angle \: OAD \: = \angle \: OCD$ </u>

<em>Solution:</em>

Join the points O and B and draw OB,

On joining the line,

in ∆OCD and ∆OBD,

OC =OB → (Radius of same circle)

BD =CD → (from given)

OD =OD → (Common side in both the triangles)

Hence ∆OCD and ∆OBD are congruent from SSS property.

so we can say that,

$\angle \: OBD \: = \angle \: OCD$

Consider above prove as statement A

Corresponding angles of congruent traingle.

in ∆ OAB,

OA = OB (radius of same circle)

hence ∆OAB is an isosceles traingle.

We know that opposite angle of isosceles traingle are always equal. hence,

$\angle \: OBD \: = \angle \: OAB \\ \angle \: OAB \: = \angle \: OAD (same \: angles) \\ \angle \: OBD \: = \angle \: OAD$

Consider above prove as statement B

From Statement A & B we can say that

$\angle \: OAD \: = \angle \: OCD$

determine the vertex and axis of symmetry for the following: f(x) = 2x to the power of 2 - 12x + 24 ?

Vikki [24]

Answer:

vertex = (3,24) Axis of symmetry = 3

Step-by-step explanation:

Use the vertex formula to find x: x=-b/2(a)

x= 12/2(2) = 3 (this is your axis of symmetry)

Substitute 3 for x in the equation to get y: y = 42

Once you have both x and y you have your vertex.

Solve the following equation for x.<br><br> 12x^2-36x=0

OlgaM077 [116]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's solve for x ~

$\qquad \sf \dashrightarrow \:12 {x}^{2} - 36x = 0$

$\qquad \sf \dashrightarrow \:12 x({x}^{} - 3) = 0$

$\qquad \sf \dashrightarrow \:12x = 0 \: \: or \: \: x - 3 = 0$

$\qquad \sf \dashrightarrow \:x = 0 \: \: or \: \: x = 3$

Therefore, the possible values of x are 0 and 3
